How do you make a stem and leaf plot using whole number and decimals with repeating numbers?
I have to make a stem and leaf plot using whole numbers and decimals but it is mostly whole numbers so using the middle line as the decimal point doesn’t seem effective. Also a lot of the whole number are repeating numbers, its a big set of data. For example some of the data is 12, 12, 12, 15, 12, 13, 15, 15, 14, 15, 11, 12, 6.99…
Please help!
The key issue here is where to set the middle line. If stems are whole numbers and leaves are the first decimal place, then the first step in producing the stem and leaf plot is to present all the data to one decimal point, by rounding if necessary. Thus, 12 becomes 12.0 and 6.99 becomes 7.0.
Once the data are in this form, you construct your plot, with one row for each stem and one leaf for each number in your data. Also provide lines for stem values in the middle of your data that don’t actually appear.
For the example you have provided, the plot would be
15|0000
14|0
13|0
12|00000
11|0
10|
09|
08|
07|0
Note that I have added stems for 10, 9, and 8 although those numbers were not in your data.
